A new study suggests migraine sufferers may face a slightly higher risk of stroke after an operation. According to UPI, the risk appears greatest among those who experience "migraine with aura", where the headache also includes a visual disturbance, such as the appearance of flashing lights. The study found that people with these types of migraines have more than double the risk of stroke after surgery compared to people without migraines. Also, the odds that someone who has migraines without aura will have a stroke after surgery are still 75 percent higher than people not afflicted by migraines.upi.com/Health_News/2017/01/11/Migraine-...wochit.com
